Test Gasoline Fuel For Water and Diesel Portions

Safety note
Risk of explosion, poisoning and injury! Fuels are highly inflammable and toxic if inhaled. Fuels may cause skin damage. Fuel vapors are explosive, invisible and spread out at floor level, they are toxic if inhaled and produce giddiness and an anaesthetizing effect.

Rules of conduct and protective measures
Wear suitable protective clothing. Pay attention to national safety precautions and regulations. No fire, sparks, naked flames and smoking. Ensure the work place is adequately ventilated. Never drain or pour in fuels over assembly pits. Store drained fuel in a suitable and sealed vessel. Immediately eliminate any fuel which has flowed out.

First-aid measures
Clean moistened skin with water and soap. Change moistened clothing as quickly as possible. If fuel gets into your eyes, rinse out your eyes immediately with water and contact a doctor if necessary.
